带有图片的HTML下拉菜单

Question

我正在尝试构建一个像图像上那样的HTML菜单。我不知道该从何开始。我考虑使用最常见的ul，但是如何绘制线条呢？

我知道如何构建菜单。问题在于图片和水平线。

您可以使用 :before 和 :after 伪元素来绘制线条和箭头，以下是一个基本示例：

HTML

<ul>
    <li>
        <img src='http://openclipart.org/people/TzeenieWheenie/TzeenieWheenie_Small_blue_i_info_button.svg' />Item
        <ul>
            <li>Sub Item</li>
        </ul>
    </li><li>
        <img src='http://openclipart.org/people/TzeenieWheenie/TzeenieWheenie_Small_blue_i_info_button.svg' />Item
        <ul>
            <li>Sub Item</li>
        </ul>
    </li>
</ul>

CSS

ul, li {
    list-style:none;
    margin:0;
    padding:0;
}
ul {
    background: rgb(238, 238, 238);

我认为他在询问如何将图像作为父链接包含在内。然后添加一行来区分子链接和父链接。 - leigero

+1 现在这是一个漂亮的小提琴！这个例子做得很好。 - leigero

谢谢。我会尝试一下。需要做些小调整。之后我会接受你的答案。 - user3070462

@SW4，是否可以设置图像和文本的链接，以便菜单项的整个区域都可以点击？ - user3070462
